這裡將詳細地對示例性實施例進行說明，其示例表示在圖式中。下面的描述涉及圖式時，除非另有表示，不同圖式中的相同數字表示相同或相似的要素。以下示例性實施例中所描述的實施方式並不代表與本說明書相一致的所有實施方式。相反，它們僅是與如所附申請專利範圍中所詳述的、本說明書的一些方面相一致的裝置和方法的例子。
在本說明書使用的術語是僅僅出於描述特定實施例的目的，而非旨在限制本說明書。在本說明書和所附申請專利範圍中所使用的單數形式的“一種”、“所述”和“該”也旨在包括多數形式，除非上下文清楚地表示其他含義。還應當理解，本文中使用的術語“和/或”是指並包含一個或多個相關聯的列出項目的任何或所有可能組合。
應當理解，儘管在本說明書可能採用術語第一、第二、第三等來描述各種資訊，但這些資訊不應限於這些術語。這些術語僅用來將同一類型的資訊彼此區分開。例如，在不脫離本說明書範圍的情況下，第一資訊也可以被稱為第二資訊，類似地，第二資訊也可以被稱為第一資訊。取決於語境，如在此所使用的詞語“如果”可以被解釋成為“在……時”或“當……時”或“回應於確定”。
區塊鏈技術，是一種由若干台計算設備共同參與“記帳”，共同維護一份完整的分布式數據庫的新興技術。由於區塊鏈技術具有去中心化、公開透明、每台計算設備可以參與數據庫記錄、並且各計算設備之間可以快速的進行數據同步的特性，利用區塊鏈技術來搭建去中心化系統，並在區塊鏈的分布式數據庫中收錄各種執行程式進行自動執行，已在眾多的領域中廣泛的進行應用。例如，在金融科技領域，利用區塊鏈技術可以搭建匯款系統，從而實現資金快速轉移，特別是跨境匯款場景中，利用區塊鏈技術搭建的匯款系統，可以實現弱信任多方參與機構間如不同國家或者地區之間的銀行的協同，進而減少匯款等待時間，提升匯款效率。由於全部的匯款記錄都以不可篡改的方式儲存於區塊鏈帳本中，可以保證整個匯款過程全鏈路透明可靠。
在本說明書中提供的匯款系統中，區塊鏈中可以儲存匯款鏈路的若干成員（Menber），以及該匯款鏈路之外的其他成員的資訊，這些成員可以為該區塊鏈上的節點。
在一實施例中，匯款鏈路的成員可以為支持匯款業務的金融機構或者其他形式的組織或平台等，本說明書並不對此進行限制。其中，以金融機構為例，匯款鏈路內各個成員可以屬於不同機構（例如多家銀行），也可以屬於同一機構的不同分支機搆（例如同一銀行的多家分行），本說明書並不對此進行限制。
由於區塊鏈採用分布式記帳的形式，且各個節點均保存全量記帳資訊，而且區塊鏈的所有節點可以通過共識演算法達成一致，共同維護了一個統一帳本，即區塊鏈帳本。因此，本說明書中描述某一成員針對“區塊鏈帳本”實施資訊的讀取或記錄時，該成員具體可以是針對自身保存的全量記帳資訊實施資訊的讀取或記錄。
以下可以結合圖1所示的例子介紹本說明書一種實現資金流動報表生成的方法的實施例，如圖1所示，該方法可以包括以下步驟：
步驟110：監管成員接收到區塊鏈上目標成員的資金流動報表生成請求。
本實施例中，監管成員可以向資金流動系統中成員提供資金流動報表服務。一般的，成員可以向監管成員發送資金流動報表生成請求，該監管成員在接收到目標成員發送的資金流動報表生成請求後，執行後續步驟。
在一實施例中，該目標成員為區塊鏈中登記的該監管成員具有管轄權限的成員。
在實際應用中，資金流動系統中可以存在多個不同的監管成員，並且不同監管成員可以管轄的成員也可以是不同的。以跨境匯款為例，本國的監管成員一般只可以監管本國的成員，而不能監管他國的成員。為此，該區塊鏈中，可以預先登記有監管成員與其具有管轄權限的成員之間的對應關係。這樣，目標成員僅可以向管轄它的監管成員發起報表生成請求；而監管成員也僅可以對具有管轄權限的目標成員進行資金流動報表生成的操作。
在一實施例中，該資金流動類型可以包括匯款、付款或者收款等。
步驟120：從該區塊鏈中獲取該目標成員的資金流動數據。
在一實施例中，由於區塊鏈採用分布式記帳的形式，且各個成員均保存全量記帳資訊，因此，監管成員可以從區塊鏈中獲取該目標成員的資金流動數據。
在一實施例中，該區塊鏈中獲取的資金流動數據包括單不限於資金流動相關、用戶資訊、交易相關性資訊的摘要數據。
在該根據設定的報表模版中參數，從所獲取的資金流動數據中匹配到參數對應的數據之前，該方法還包括：
從該目標成員處獲取該摘要數據對應的資金流動詳細數據；
根據該資金轉流詳細數據生成用於校驗數據完整性的第二摘要數據；
該根據設定的報表模版中參數，從所獲取的資金流動數據中匹配到參數對應的數據，具體包括：
在該第二摘要數據與該區塊鏈中獲取的摘要數據一致的情況下，根據設定的報表模版中參數，從該資金流動詳細數據中匹配到參數對應的數據。
該實施例中，區塊鏈對於一些涉及成員隱私的數據，並不會直接進行記錄，從而僅記錄該隱私數據的摘要數據，而原始數據是記錄在成員本地的。該摘要數據一般可以是通過區塊鏈中統一使用的演算法（例如哈希演算法）計算出的一個數位摘要，僅通過這個數位摘要是無法解讀出真實數據的。在實際應用中，如果其它成員需要獲取摘要資訊的原始數據，可以向該摘要資訊對應的成員獲取，當獲取到原始數據後，還需要核對數據有效性，即基於統一使用的演算法，再次計算出該原始數據的摘要資訊，將計算出的摘要資訊與區塊鏈上的摘要資訊進行比對，一致說明獲取的原始數據完整，不一致說明獲取的原始數據存在異常。通過該實施例，可以保證監管成員所獲取的資金流動詳細數據的有效性。
在一實施例中，該從該區塊鏈中獲取該目標成員的資金流動數據，具體包括：
向該區塊鏈發起獲取資金流動數據的合約操作；該合約操作用於從區塊鏈中獲取該目標成員的資金流動數據。
區塊鏈內的成員在加入智能合約後，可以對該智能合約支持的若干合約操作進行調用，比如此處的“獲取資金流動數據的合約操作”的合約操作。監管成員向區塊鏈發起合約操作，並在該合約操作實現後，就可以獲取到該目標成員的資金流動數據。
在一實施例中，該請求中還攜帶有開始時刻和結束時刻；
該從該區塊鏈中獲取該目標成員的資金流動數據，具體包括：
從該區塊鏈中獲取該目標成員在該開始時刻和結束時刻之間的資金流動數據。
步驟130：根據設定的報表模版中參數，從所獲取的資金流動數據中匹配到參數對應的數據。
該報表模版通常可以由若干參數構成。例如，某報表模版可以包括區塊鏈帳本中登記的成員每一筆資金流動操作時間，操作類型（收款、匯款、轉帳、支付等），操作前餘額，操作後餘額，淨額變動結果（餘額是增還是減）等。該報表模版還可以設置有某些篩選條件，例如只獲取操作金額大於5000元的記錄。
步驟140：將匹配到的數據寫入到該報表模版中，生成該成員目標的資金流動報表。
步驟150：將該資金流動報表推送給該目標成員。
監管成員可以根據請求中攜帶的目標成員的地址（如IP、MAC等），將該資金流動報表推送給該目標成員。
通過該實施例，提供一種基於區塊鏈技術構建的資金流動系統。利用區塊鏈不可篡改的特點，區塊鏈會記錄的每一筆資金流動數據都是真實、完整的。監管成員在接收到目標成員發送的資金流動報表生成請求後，直接從區塊鏈中獲取到的資金流動數據必定是真實、完整的，進而基於這樣的資金流動數據生成的報表也同樣是真實完整的。
以下可以結合圖2所示的例子介紹本說明書一種實現資金流動報表生成的方法的實施例，如圖2所示，該方法可以包括以下步驟：
步驟210：區塊鏈的成員觸發資金流動報表生成指令。
在一實施例中，該資金流動報表生成指令的觸發條件為：達到設定週期時；即區塊鏈的成員可以週期性生成資金流動報表。該週期可以是預設的一個經驗值，例如1天、1周、1月等。
在一實施例中，該資金流動報表生成指令的觸發條件為：
接收到輸入的包括開始時刻和結束時刻的資金流動報表生成指令。例如，成員可以根據人為輸入的指令生成資金流動報表。
在一實施例中，該資金流動類型包括匯款、付款或者收款。
步驟220：從該區塊鏈中獲取本成員的資金流動數據以及報表模版。
在一實施例中，該從該區塊鏈中獲取本成員的資金流動數據以及報表模版，具體包括：
向該區塊鏈發起獲取資金流動數據的合約操作；該合約操作用於從區塊鏈中獲取本成員的資金流動數據以及報表模版。
在一實施例中，針對，該資金流動報表生成指令的觸發條件為：
達到設定週期時；
該從該區塊鏈中獲取本成員的資金流動數據，具體包括：
從該區塊鏈中獲取本成員在該週期內的資金流動數據。
在一實施例中，針對，該資金流動報表生成指令的觸發條件為：
接收到輸入的包括開始時刻和結束時刻的資金流動報表生成指令。
該從該區塊鏈中獲取本成員的資金流動數據，具體包括：
從該區塊鏈中獲取本成員在該開始時刻和結束時刻之間的資金流動數據。
在一實施例中，該報表模版為區塊鏈中監管成員發佈的。
監管成員具有發佈報表模版的功能，監管成員可以向區塊鏈發起報表模版發佈的合約操作，從而將報表模版廣播到區塊鏈，以使區塊鏈中成員更新本地區塊鏈記錄的報表模版。
值得一提的是，監管成員還可以修改已發佈報表模版中參數。類似的，監管成員可以向區塊鏈發起報表模版參數修改的合約操作，從而將修改前參數和修改後參數廣播到區塊鏈，以使區塊鏈中成員將本地區塊鏈記錄的報表模版中參數進行修改。
在一實施例中，資金流動系統中可以存在多個不同的監管成員，並且不同監管成員可以管轄的成員也可以是不同的。也就是說，區塊鏈中可能記錄有不同監管成員發佈的不同的報表模版；因此，所述從該區塊鏈中獲取報表模版，具體包括：
從該區塊鏈中獲取本成員對應的監管成員發佈的報表模版。
步驟230：根據該報表模版中參數，從該資金流動數據中匹配到參數對應的數據。
在一實施例中，該區塊鏈中獲取的資金流動數據包括單不限於資金流動相關、用戶資訊、交易相關資訊的摘要數據；
在該根據設定的報表模版中參數，從所獲取的資金流動數據中匹配到參數對應的數據之前，該方法還包括：
從本地獲取該摘要數據對應的資金流動詳細數據；
該步驟230，具體包括：
根據該報表模版中參數，從該資金流動詳細數據中匹配到參數對應的數據。
步驟240：將匹配到的數據寫入到該報表模版中，生成該成員目標的資金流動報表。
通過本實施例，區塊鏈中成員可以生成自己的資金流動報表；而無需經由前述實施例那樣必須由監管成員完成。
與前述資金流動報表生成方法實施例相對應，本說明書還提供了資金流動報表生成裝置的實施例。該裝置實施例可以通過軟體實現，也可以通過硬體或者軟硬體結合的方式實現。以軟體實現為例，作為一個邏輯意義上的裝置，是通過其所在設備的處理器將非揮發性記憶體中對應的電腦程式指令讀取到內部記憶體中運行形成的。從硬體層面而言，本說明書資金流動報表生成裝置所在設備的一種硬體結構可以包括處理器、網路介面、內部記憶體以及非揮發性記憶體之外，實施例中裝置所在的設備通常根據該資金流動報表生成實際功能，還可以包括其他硬體，對此不再贅述。

應當理解的是，本說明書並不局限於上面已經描述並在圖式中示出的精確結構，並且可以在不脫離其範圍進行各種修改和改變。本說明書的範圍僅由所附的申請專利範圍來限制。The exemplary embodiments will be described in detail here, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with this specification. On the contrary, they are only examples of devices and methods consistent with some aspects of this specification as detailed in the scope of the appended application.
The terms used in this specification are only for the purpose of describing specific embodiments, and are not intended to limit the specification. The singular forms of "a", "the" and "the" used in this specification and the scope of the appended application are also intended to include plural forms, unless the context clearly indicates other meanings. It should also be understood that the term "and/or" used herein refers to and includes any or all possible combinations of one or more associated listed items.
It should be understood that although the terms first, second, and third may be used in this specification to describe various information, the information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this specification, the first information can also be referred to as second information, and similarly, the second information can also be referred to as first information. Depending on the context, the word "if" as used herein can be interpreted as "when" or "when" or "in response to certainty".
Blockchain technology is an emerging technology in which several computing devices participate in "bookkeeping" and jointly maintain a complete distributed database. Because the blockchain technology has the characteristics of decentralization, openness and transparency, each computing device can participate in database records, and the data can be synchronized quickly between computing devices, the blockchain technology is used to build a decentralized system, and Various execution programs are included in the distributed database of the blockchain for automatic execution, which has been widely used in many fields. For example, in the field of financial technology, blockchain technology can be used to build a remittance system to achieve rapid transfer of funds, especially in cross-border remittance scenarios. The use of blockchain technology to build a remittance system can achieve weak trust among multi-party institutions such as The coordination of banks in different countries or regions can reduce the waiting time for remittance and improve the efficiency of remittance. Since all the remittance records are stored in the blockchain ledger in an immutable way, it can ensure that the entire remittance process is transparent and reliable.
In the remittance system provided in this manual, the blockchain can store several members of the remittance link (Menber), as well as the information of other members outside the remittance link. These members can be nodes on the blockchain .
In an embodiment, the members of the remittance link may be financial institutions or other forms of organizations or platforms that support the remittance business, and this specification does not limit this. Among them, taking a financial institution as an example, each member in the remittance link can belong to different institutions (such as multiple banks), or belong to different branches of the same institution (such as multiple branches of the same bank). This manual does not describe this limit.
Because the blockchain adopts the form of distributed accounting, and each node saves the full amount of accounting information, and all nodes of the blockchain can reach an agreement through the consensus algorithm, and jointly maintain a unified ledger, the blockchain ledger. Therefore, when a member is described in this specification to read or record information for the "blockchain ledger", the member can specifically read or record information for the full amount of accounting information stored by the member.
The following can be combined with the example shown in FIG. 1 to introduce an embodiment of a method for generating a capital flow statement in this specification. As shown in FIG. 1, the method may include the following steps:
Step 110: The supervisory member receives a request for generating a capital flow statement from the target member on the blockchain.
In this embodiment, the supervisory member can provide the fund flow report service to the members in the fund flow system. Generally, a member can send a fund flow statement generation request to a supervising member, and the supervising member performs the subsequent steps after receiving the fund flow statement generation request sent by the target member.
In an embodiment, the target member is a member registered in the blockchain and the supervisory member has jurisdiction.
In practical applications, there may be multiple different regulatory members in the capital flow system, and the members that can be governed by different regulatory members may also be different. Taking cross-border remittances as an example, the supervisory members of their own country can generally only supervise members of their own country, but not members of other countries. For this reason, the corresponding relationship between supervisory members and members with jurisdiction can be pre-registered in the blockchain. In this way, the target member can only initiate a report generation request to the supervisory member that governs it; and the supervisory member can only generate the capital flow report for the target member with jurisdiction.
In an embodiment, the type of fund flow may include remittance, payment, or receipt.
Step 120: Obtain the fund flow data of the target member from the blockchain.
In one embodiment, since the blockchain adopts the form of distributed accounting, and each member saves the full amount of accounting information, the supervisory member can obtain the fund flow data of the target member from the blockchain.
In one embodiment, the capital flow data obtained in the blockchain includes but not limited to summary data related to capital flow, user information, and transaction-related information.
Before matching data corresponding to the parameters from the acquired capital flow data according to the parameters in the set report template, the method further includes:
Obtain detailed capital flow data corresponding to the summary data from the target member;
Generate second summary data for verifying the integrity of the data according to the detailed fund transfer data;
According to the parameters in the set report template, the data corresponding to the parameters are matched from the obtained capital flow data, including:
In the case that the second summary data is consistent with the summary data obtained in the blockchain, the data corresponding to the parameter is matched from the detailed capital flow data according to the parameters in the set report template.
In this embodiment, the blockchain does not directly record some data related to member privacy, so that only summary data of the private data is recorded, and the original data is recorded locally. The summary data can generally be a digital summary calculated by an algorithm (for example, a hash algorithm) that is uniformly used in the blockchain, and the real data cannot be interpreted by this digital summary alone. In practical applications, if other members need to obtain the original data of the summary information, they can obtain it from the member corresponding to the summary information. When the original data is obtained, the validity of the data needs to be checked. That is, based on the uniformly used algorithm, calculate again The summary information of the original data is obtained, and the calculated summary information is compared with the summary information on the blockchain. The agreement indicates that the original data obtained is complete, and the inconsistency indicates that the original data obtained is abnormal. Through this embodiment, the validity of detailed capital flow data obtained by supervisory members can be guaranteed.
In an embodiment, the obtaining the target member's fund flow data from the blockchain specifically includes:
Initiate a contract operation to obtain fund flow data to the blockchain; the contract operation is used to obtain the target member's fund flow data from the blockchain.
After the members of the blockchain join the smart contract, they can call several contract operations supported by the smart contract, such as the contract operation of "Contract Operation for Obtaining Fund Flow Data" here. The supervisory member initiates a contract operation to the blockchain, and after the contract operation is implemented, the target member's fund flow data can be obtained.
In an embodiment, the request also carries a start time and an end time;
The fund flow data of the target member should be obtained from the blockchain, including:
Obtain the fund flow data of the target member between the start time and the end time from the blockchain.
Step 130: According to the parameters in the set report template, match the data corresponding to the parameters from the obtained fund flow data.
The report template can usually consist of several parameters. For example, a report template can include the operation time of each fund flow of members registered in the blockchain ledger, the type of operation (receiving, remittance, transfer, payment, etc.), the balance before the operation, the balance after the operation, and the net change result ( Does the balance increase or decrease) etc. The report template can also be set with certain filtering conditions, such as only obtaining records with an operation amount greater than 5,000 yuan.
Step 140: Write the matched data into the report template, and generate a fund flow report for the member's target.
Step 150: Push the fund flow report to the target member.
The supervisory member can push the fund flow report to the target member according to the address (such as IP, MAC, etc.) of the target member carried in the request.
Through this embodiment, a fund flow system based on blockchain technology is provided. Utilizing the non-tamperable feature of the blockchain, every capital flow data recorded by the blockchain is true and complete. After the supervisory member receives the fund flow report generation request sent by the target member, the fund flow data directly obtained from the blockchain must be true and complete, and the report generated based on such fund flow data is also true and complete of.
